Yes, theoretically all tenants have certain rights, such as painting every three years and heat. But the landlord can decide not to renew the lease of tenants who are not protected by regulation, so they are taking a risk if they try to exercise those rights.

> Some of the things you talk about (heat, painting) are covered by the basic building code, not the rent regulation, so you do have a right to them. The rules should be somewhere in the reference section of this site.
